PetVille’s getting into the St. Patrick’s Day spirit by tasking players with finding four-leaf clovers in a brand new mini-game. If you see a big green clover hanging around your pet’s house, click on it and that will launch a game, and the goal of this game is to pick which patch contains the lucky four-leaf clover. You have three tries, and if you choose correctly, you will be rewarded with special St. Patty’s Day loot.
